My Ryobi conversion started life as a Lawn Boy. I bought it new in 1985. But it wasn't long before Ryan's were every where. They disappeared and Ryobi's showed up. But I think some of the Sears whackers are Ryobi's. There are some Toro's and Stihls that make you wonder? What about the Cub Cadet? That's a name that MTD has owned for years. Then there are the MTD names like Yard Man, Lawn Chief, Arnold, among others?

When you see an engine with a counter levered crankshaft, that is mounted upside down, with reed valve induction, and claims a capacity of between 30 and 32cc, it's probably a Ryobi?

Ryobi also has made a couple different four strokes... And they make a smaller two stroke? Cannot remember the size? seemed to be better made than the "31"?

There's another name associated with Ryobi and that's IDC. They were listed as the owners for many years.

Then there are the many models of the engines labeled as Ryobi's?

Enjoy,

Jim
